Here's the formula for the best penetrating oil (from a Forum post I can't relocate):
The April/May 2007 edition of Machinist's Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Mighty interesting results for simple acetone and tranny fluid!
Penetrating oil .. Average load .. Price per fluid ounce
None ................. 516 pounds ..
WD-40 .............. 238 pounds .. $0.25
PB Blaster ......... 214 pounds .. $0.35
Liquid Wrench ... 127 pounds .. $0.21
Kano Kroil ......... 106 pounds .. $0.75
ATF-Acetone mix.. 53 pounds .. $0.10
The ATF-Acetone mix was a 50/50 mix (1 to 1 ratio).

Where is the thermostat housing on a 99 Chevy Malibu?
If it is like my 2000 Malibu V6, this housing is located behind the exhaust crossover pipe. This is the pipe from the front exhaust manifold to the rear exhaust manifold. If you remove the air intake ducts and and airflow meter, you will get a better view of the housing, the top radiator hose is attached to it. If you remove the exhaust crossover pipe, it will be a lot easier to remove this housing. I believe you can remove the housing without removing the crossover pipe, but it will be a little trickier, especially upon installaltion. The bolt sizes are either 10mm or 8mm, don't exactly recall. The bolt sizes on the exhaust crossover are 13mm, a deep socket is needed here.
